Abstract (en)
[origin: US5345007A] A process for the preparation of octadienols, comprising the hydrodimerization reaction of 1,3-butadiene with water in the presence of a transition metal in the metal form or in the form of a compound of the said metal, of a water-soluble tertiary or quaternary phosphorus-containing compound and of at least one nitrogen-containing compound selected from the group consisting of a tertiary amine and a quaternary ammonium salt of general formula (I) or (II): <IMAGE> (I) <IMAGE> (II) in which Rp, Rq and Rs are identical or different and each is a methyl or ethyl group; Rr is an alkyl group containing from 6 to 22 carbon atoms; X is a counter-anion selected from the group consisting of HCO3-, CO32-, HSO3-, SO32-, SiO32-, PO43-, HPO32-, AsO43-, SO42-, HSO4-, RSO3-, RCO2-, and OH-, R being an alkyl group; the said reaction being carried out in the presence of carbon dioxide.
